Re: low noise amplifier
Hi Ferdian Cahyodwiputro. I created a small electronic circuit to test the model. Using this scheme, I found that the description of the transistor pins are in non-standard order. I will put circuit

Re: A TVS does not work with load dump test??
Important intuitive point - TVS does not have sharp breakdown like a zener. Note, carefully Bordodynov's specs. Breakdown (probably at 10-100mA) of 26.7V to 29.5V. Conduction voltage rises 9V by the

All you get it right. Carefully study the documentation for the complete set. Datasheet ----> Breakdown Voltage Vbr=26.7- 29.5V, Clamping Voltage Vc=38.9V at IPPM=15.4A Bordodynov. 10.07.2013, 09:46,

Re: A TVS does not work with load dump test??
Thanks for everyone's suggestion, I put a new TVS from the LTspice library(SMBJ24CA) and set a series resistance(0.5 ohm) for the voltage source. the simulation result shows the voltage is clamped at

Re: A TVS does not work with load dump test??
Everything said here is correct. The voltage source has precisely zero output resistance, so it will sustain the driven voltage at whatever current, no matter how hard the TVS tries to shunt it.
By Andy I · #64681 ·
Re: A TVS does not work with load dump test??
The voltage source is virtually ideal; it?has virtually no output impedance, so there is nothing across which to drop the voltage and it can supply virtually infinite current. The current through the
